By default, when the Enter key is pressed in a form's input field, it will trigger the form to be submitted. This behaviour can be prevented with JavaScript — here's how: Listen for key presses in the input using the keydown event. Check the key pressed by reading the key property of the event object. If the key is Enter, prevent the default behaviour (triggering form submit) by calling preventDefault method on the event object. For example: document.querySelector('input') .addEventListener('keydown', (e) => { if (e.key === 'Enter') { e.preventDefault(); } }); This way, every time Enter is pressed in the form's input field, the form won't be submitted.  ( 3 min )

I have recently done two maintenance releases of the GitHub action for checking spelling. 0.50.0 on 2025-05-16 0.51.0 on 2025-05-20 I did one as the base image was updated and could might aswell ship it, since not much else was planned. From the change log for 0.50.0: Docker image updated to Python 3.13.4 slim via PR #246 from Dependabot. Release notes for Python 3.13.4 A few days after a PR for updating the base image again came in. From the change log for 0.51.0: Docker image updated to Python 3.13.5 slim via PR #249 from Dependabot. Release notes for Python 3.13.5 Release 0.49.0 was made on 2025-05-22 and prior to that 0.48.0 on 2025-04-01, so I was satisfied with the monthly cadence of releases. But the world around us changes constantly, so I thought I might as well keep up and get the chore done. For myself this results in a bunch of PRs to review and merge, next week when Dependabot notifies me of the 0.51.0, but I can live with that and I can handle it on my commute to work on the phone. I hope it is not too much inconvenience for the other users of the action.  ( 3 min )

When you're learning React, one concept you’ll often come across is props drilling. At first, it might seem confusing—but once you understand what’s happening, it’s quite straightforward. Let’s break it down. Props Drilling is when you pass data from a parent component down to deeply nested child components using props—even if the intermediate components don’t actually need that data. This often leads to bloated and harder-to-maintain code, especially in large apps. Imagine you have this component structure: App → Parent → Child → GrandChild Now, let's say App has some data that GrandChild needs. Here’s what props drilling would look like: function App() { const user = "Tamilselvan"; return ; } function Parent({ user }) { return ; } function Child({ user }) { return ; } function GrandChild({ user }) { return Hello, {user}! ; } Notice how Parent and Child don’t use the user prop, but they still have to pass it along just so GrandChild can use it. That’s props drilling. Hard to maintain – Changing the data structure means updating multiple components. Cluttered code – Components get unnecessary props. Performance issues – Every component in the chain re-renders when the prop changes. React Context API Share data across components without manually passing props. const UserContext = React.createContext(); function App() { return ( ); } function GrandChild() { const user = useContext(UserContext); return Hello, {user}! ; } State management tools Like Redux, Zustand, or Recoil for large-scale apps. Props drilling isn’t always bad—it’s just a sign that your app might need a better way to manage shared state. For small apps, it’s totally fine. But as your component tree grows, learning tools like Context API becomes essential.  ( 4 min )

The Unsung Hero: Mastering Callbacks in Production Node.js Introduction We were onboarding a new payment processor into our microservices architecture. The processor’s Node.js SDK relied heavily on callbacks for asynchronous operations – specifically, handling webhooks for transaction status updates. Initial integration attempts resulted in intermittent failures, lost updates, and a cascade of support tickets. The root cause wasn’t the processor’s SDK itself, but our team’s insufficient understanding of callback management in a high-throughput, distributed system. This isn’t an isolated incident. Callbacks, while foundational, are often treated as a solved problem, leading to subtle but critical issues in production Node.js applications. This post dives deep into callbacks, …  ( 7 min )

Hi there! I’m Kaden, a 16-year-old developer building an AI assistant called CODA: A Creative Optimization & Development Assistant. CODA is designed to create, edit, and optimize code by analyzing your entire project—because it actually has local access to your files. This means it can give advice that makes sense in the full context of your work, not just a single file or snippet. I started building CODA a couple of weeks ago, and I’ll be honest—I'm not some genius. I used ChatGPT a lot to help write the code. But soon, I hope to rely on CODA alone. Right now, I'm in Phase 2, where CODA can read all files in your project, understand and generate code based on the full context, and offer targeted coding advice. My plan for the future is to make a smart debugger, an improved memory system (because I'm currently using .json files), Text-to-speech, speech-to-text, and even a wake word so it starts feeling more like JARVIS. If you'd like to stick around, I’ll be posting another update when Phase 2 is complete, and outlining the roadmap for Phase 3. Thanks for reading! Let me know what you think, and if you know any ways I can optimize my progress, I'd love to hear them.  ( 3 min )

As a developer who has lived and breathed React for years, I've always been skeptical of new frameworks promising to be "the next big thing." But the buzz around Svelte and SvelteKit finally got to me. I spent a weekend rebuilding my portfolio with it. Here are three "aha!" moments that genuinely surprised me. The Disappearing Framework State Management is Just... JavaScript let count = 0; function handleClick() { That's it. This simplicity felt almost too easy at first, but it's incredibly refreshing. File-based Routing Feels Like Cheating SvelteKit's file-based routing (similar to Next.js) is a joy to work with. Creating a new page is as simple as creating a new +page.svelte file in your routes directory. Loading data for that page is done in a sibling +page.server.js file. It's intuitive, co-located, and makes the entire structure of the app easy to reason about. I'm not abandoning React tomorrow, but my skepticism is gone. SvelteKit offers a fantastic developer experience and incredible performance. If you're a React dev on the fence, I highly recommend giving it a try. What are your thoughts on SvelteKit?  ( 4 min )

So I was working on some benchmarking with a piece of code in JavaScript and I was scratching my head over the runtimes that I was seeing. I literally could not make sense of what was happening. And in a wild attempt at debugging, I stumbled upon a quirk that I had never known. The v8 engine does not really like the delete operator. And using this operator on an object can have a tangible impact on the performance of your code. In my case, it was almost 3 times worse performance than if I had manually set that key to undefined or false That said, I was able to reproduce this in Safari v18.5 as well along with all Chromium based browsers. So not really sure if this behavior is limited to the v8 engine. Here’s a simple code I wrote based on my experience to easily benchmark the performance i…  ( 4 min )

🐙 GitHub Pattern matching in TypeScript has become an essential part of my daily workflow, both in React and Node.js. Personally, I haven't found a need for switch-case statements—I can't even recall the last time I used one. In this post, I'll share practical pattern matching techniques that I rely on regularly. All the reusable code can be found in the GitHub repository. Often, when we reach for a switch-case statement, our real goal is to run different logic depending on the value of a union type or enum. For example, in a music theory app, we need to generate different note patterns for different scale types. Each scale type—like blues, full, or pentatonic—has its own function that implements the specific logic for that scale, but all of these functions share the same input and output…  ( 11 min )

Understanding Functional Programming Functional programming is a programming style or paradigm that focuses on building software by creating and combining functions. Think of it like this: you write small, self-contained pieces of code (functions) that take an input, perform some operations, and then produce an output. A core idea is that for the same input, you will always get the same output, making the code predictable. Reusable: Functions are designed to be independent, meaning you can easily reuse them across different parts of your code or in various modules, as long as you need their specific output. Stateless: Functional programs aim to be "stateless." This means a function's output depends solely on its inputs, not on any changeable internal or external state. No matter how man…  ( 6 min )

Think of them like templates or blueprints—not code that you copy and paste, but rather ideas and structures that guide you in solving recurring problems in a clean, efficient, and maintainable way. Design patterns generally fall into three broad categories, each addressing a different kind of software design problem: 1. Creational Patterns object creation mechanisms, trying to create objects in a manner that is suitable to the situation. They help make a system independent of how its objects are created, composed, and represented. Examples: Singleton, Factory Method, Builder, Abstract Factory, Prototype 2. Structural Patterns composed to form larger structures. They help ensure that if one part of a system changes, the entire system doesn't need to do the same. Examples: Adapter, Composite, Proxy, Decorator, Bridge, Facade 3. Behavioral Patterns communication between objects, focusing on the responsibilities and the flow of control in a program. Examples: Observer, Strategy, Command, State, Iterator, Mediator In the upcoming posts, I’ll break down each design pattern—complete with real-world analogies, use cases, pros & cons, and practical examples in code. Whether you’re a beginner developer or someone brushing up on architectural skills, this series will help you think more clearly about software design. Have you used any design patterns in your projects? Or do they still feel abstract and academic? Drop a comment below—I’d love to hear your thoughts or questions!  ( 3 min )

Last week, our CISO got phished. Yes, really. The email was so convincing that three senior managers clicked the link within minutes. That's when I realized we needed more than just "don't click suspicious links" training.

"Replaying 10,000 events just to check a balance? There’s a better way." Event sourcing gives you time-travel superpowers—until you realize: Rebuilding an aggregate from 1M events takes minutes. Your read API times out waiting for a replay. Testing becomes painfully slow. Snapshots fix this by periodically caching state, so you only replay recent events. Here’s how to implement them without breaking event-sourcing principles. 1. When Do You Need Snapshots? Problem Signs Slow reads: GET /users/123 triggers a 5-second replay. High memory usage: Event processing OOMs your pods. Frequent replays: The same aggregate is rebuilt repeatedly. Rule of Thumb Snapshots make sense when replay time > 100ms for hot aggregates. 2. Snapshot Strategies Strategy 1: Scheduled Sn…  ( 4 min )

Once every few months I do a "retest" of my JavaScript knowledge. I review sets of recruitment questions and refresh fundamentals of this language. One of the most important topics that I always review is the Event Loop. In short: it's the mechanism that allows JavaScript, despite being single-threaded, to handle asynchronous operations without blocking the main execution thread. Because of this many of our daily problems are focused on solving the valid order of synchronous and asynchronous operations we have in our programs. That being said examples like this below and similar are quite popular during the recruitment process. At least I had this topic for a few times. I don't want to focus on explaining this problem in detail. It has already been sufficiently described in many articles b…  ( 4 min )

As someone learning cloud computing and DevOps, one of my first hands-on experiences was launching an Amazon EC2 (Elastic Compute Cloud) instance and deploying a basic web server using Apache. If you are new to AWS or cloud infrastructure in general, this post will walk you through the process I followed—from spinning up an EC2 instance to seeing my first “It works!” page live on a browser. What is EC2? With EC2, you can: Choose your preferred OS (Linux, Windows, etc.) Scale up or down depending on traffic Pay only for what you use Now, let’s dive into how I used EC2 to set up a web server with Apache. Step-by-Step: Deploying EC2 with Apache Login to AWS Console Go to https://aws.amazon.com/ and sign in to the AWS Management Console. If you don’t have an account yet, sign up—it’s free to g…  ( 5 min )

Securing the Edge: A Deep Dive into IBM Bluemix Ti Board Starter Imagine a global logistics company, tracking thousands of containers across oceans and continents. Each container is a potential security risk – tampering, theft, or environmental damage. Traditional security measures are often reactive, relying on inspections at ports. Now, envision a system where each container actively reports its status, location, and integrity in real-time, triggering alerts the moment something is amiss. This is the power of edge computing, and securing it is paramount. IBM Bluemix Ti Board Starter is a key enabler for this kind of proactive, secure edge deployment. Today, businesses are increasingly adopting cloud-native applications, embracing zero-trust security models, and navigating the complexi…  ( 11 min )

Seu sistema está lento, travando sob carga ou apresentando falhas em cascata? Um dos culpados pode ser a ausência de um mecanismo crucial: Back Pressure. Em sistemas distribuídos, componentes se comunicam constantemente. Um producer (upstream) envia dados para um consumer (downstream) processar. Mas o que acontece quando o producer é muito mais rápido que o consumer? O consumer fica sobrecarregado, sua fila de processamento explode, a memória estoura e o sistema inteiro pode cair. É aqui que entra o Back Pressure. Back Pressure é um mecanismo de feedback que permite ao componente consumer (sobrecarregado) sinalizar ao producer (rápido demais) para que ele diminua o ritmo ou pare de enviar dados temporariamente. Pense nisso como um controle de tráfego. Em vez de deixar os dados fluírem sem …  ( 5 min )

Project Structure Overview and Login Flow In part one, we gained an overview of the directory structure and the packages we will install for the project. Now, we’ll discuss the login flow, which will be implemented as follows: Opening the App: If the user is not logged in: Display the Login Screen. The user taps “Login with Apple” to initiate the login process on their iPhone. 2. Searching for the User based on the account: If the user does not exist: Create a new user and proceed. If the user exists and is valid: Retrieve the valid user information and proceed. If the user exists but is invalid: Display an error. 3. Returning to the App: Store the login information in Context. If the user is valid, navigate to the Home Screen. If the user is invalid, navigate to the Error Screen. 4. W…  ( 8 min )

A Duet of Performance and Safety: Technical Analysis of Modern Web Frameworks As a third-year computer science student immersed in the world of computer science, my days are consumed by the logic of code and the allure of algorithms. However, while the ocean of theory is vast, it's the crashing waves of practice that truly test the truth. After participating in several campus projects and contributing to some open-source communities, I've increasingly felt that choosing the right development framework is crucial for a project's success, development efficiency, and ultimately, the user experience. Recently, a web backend framework built on the Rust language, with its earth-shattering performance and unique design philosophy, completely overturned my understanding of "efficient" and "moder…  ( 6 min )

Hi there! I'm Maneshwar. Right now, I’m building LiveAPI, a first-of-its-kind tool that helps you automatically index API endpoints across all your repositories.

In existing logging libraries, including Go’s built-in log/slog logging library, they typically support log file rotation and splitting. However, these features are not built in directly—they need to be actively configured by us to enable them. This article will explore several popular logging libraries, such as logrus, zap, and the official slog. We will analyze the key design elements of these libraries and discuss how they support the configuration of log rotation and splitting. When comparing the design of logrus, zap, and slog, one prominent commonality is that they all include the crucial property of io.Writer. This property plays a central role in the design of logging frameworks, as it determines the target location for log output. logrus is a feature-rich logging library for Go, p…  ( 7 min )

LeetCode, Codewars, and similar sites that "test your skill" as a developer aren't good interview tools, but they can be good personal skill builders. Rather than highlighting developers who can follow direction and solve problems, using sites like these as skill-validation tools can strongly favor developers who memorized the answer rather than developers who can demonstrate skill in reading requirements, following instructions, and solving problems. Don't get me wrong; knowing the answer is an important part of development. Not reinventing the wheel saves us time, complexity, and risk. But there are different aspects of the role of developer, and knowing about a linked list is different than demonstrating the ability to recreate one while racing a clock. As a personal development tool, s…  ( 4 min )

This is a submission for Frontend Challenge - June Celebrations, CSS Art: June Celebrations. World Sea Turtle Day (June 16) celebrates these ancient mariners who have navigated Earth's oceans for over 100 million years. Sea turtles are incredible creatures that face numerous threats, from plastic pollution to climate change. This CSS art honors their graceful swimming patterns and the underwater world they call home. Journey This piece challenged me to recreate the elegant motion of sea turtles gliding through water. I used CSS animations to simulate their distinctive swimming pattern - the way they gracefully move their flippers in a synchronized rhythm. The turtle shapes are created entirely with CSS, using clever combinations of border-radius, transforms, and pseudo-elements. The underwater environment features floating seaweed created with CSS animations and a gradient background that mimics the way sunlight filters through ocean water. I experimented with different animation delays to make each turtle move independently, creating a more natural scene. What I'm most proud of is the organic feel of the animations - they don't feel robotic or mechanical. The turtles seem to truly "swim" through their digital ocean. In future iterations, I'd love to add bubbles, more diverse marine life, and perhaps simulate the turtle's journey from nest to ocean.  ( 3 min )

At Tigris Data, we provide object storage to our users. People put bytes into our servers with a name, and expect that come hell and high water, when they put in the name, they get the exact same bytes back. This is a very high trust position to be in because when people ask themselves things like “Oh, what would happen if my object storage provider is unreliable”, that conversation usually involves phrases like “Maybe we should have gone with The Big Cloud afterall”. Such conversations are rarely good for the business. If you store your data in Tigris, you shouldn’t need to worry about a status page full of green checkmarks or anything else that needs to be updated manually. As a result, we’re trying something different. We’re making our internal reliability and performance metrics publi…  ( 5 min )

This is a submission for the Runner H "AI Agent Prompting" Challenge I built a super simple but surprisingly useful Runner H agent called “Meeting to Google Docs”. The goal? Just type in the details of your meeting, and boom — Runner H creates a clean, ready-to-use Google Doc titled with the meeting name and structured with your agenda. This agent is for anyone (like me!) who constantly has to jot down meeting notes, agendas, or brainstorms and just wants to skip the repetitive formatting and file creation. It takes 10 seconds instead of 10 minutes. runner.hcompany.ai How I Used Runner H Here’s how I set it up: Runner H instantly created a well-formatted Google Doc in my Drive — no extra clicks, no templates, no chaos. You can easily replicate this by typing your own meeting title and points — that’s it! No code, no learning curve. If you’ve ever scrambled 2 minutes before a call to create a doc, or juggled messy notes across apps, this is your fix. It’s great for: It doesn’t try to do everything — just one thing really well. And that’s the magic. ✨ I’ll be sharing this on Twitter and LinkedIn soon — will update with links here once it’s live!  ( 3 min )

The world of modern web development is evolving. Now we're not talking about the notorious race of everyday emerging front-end frameworks or about the environments that have walked the path from text editors to powerful plugin-rich and adjustable IDEs for any purpose. LLMs are gaining power and becoming better and better so there are two ways to deal with it - deny it or accept it. In order to keep up with the more and more increasing speed of development it's always nice to revisit the current state of events and check new cool kids on the block. Nowadays the development process has become more like a copy-paste from the error trace to GPT and back. The tools are powerful, but we still require the middleman to handle all of them, to give the context. Context is still something we're tryin…  ( 5 min )

As I continue my journey through the world of Web3, I’ve been digging into the building blocks that make privacy-first platforms like Midnight possible (you can catch up on previous posts in the Midnight Dev Diaries!). This week, I focused on two foundational pieces that go hand in hand: smart contracts on Midnight and the Compact language that powers them. Smart contracts aren’t new to blockchain, but Midnight’s approach is unique. Instead of executing code directly on-chain, Midnight uses smart contracts to define rules that are enforced off-chain through zero-knowledge proofs. At the center of this system is Compact—a purpose-built language designed to make writing these privacy-preserving contracts both secure and practical. To better understand how this works in practice, I also worke…  ( 7 min )

TL;DR: Borderlands 4 has dodged the dreaded $80 launch price, with its standard edition up for pre-order at $69.99 ($60/€70) ahead of its Sept. 12 release. Deluxe and Super Deluxe bundles will set you back $100 and $130, respectively, packing in post-launch DLC, skins and extra Vault Hunters. A bit of drama preceded the reveal: CEO Randy Pitchford’s flippant “If you’re a real fan, you’ll find a way to make it happen” comment on X sparked outrage, especially after he noted production costs had doubled since Borderlands 3. He’s since celebrated the $70 price on social media—some suspect it was a cheeky PR play to juice pre-orders—while other big publishers (cough Microsoft) are already eyeing $80 tags on upcoming titles.  ( 3 min )

• Introduction Mr. Uba Joseph Ugochukwu and his team in the “From Zero to Hero” python class, was my first time of hearing “The Zen of Python”. I had to do my research before I understood what it means. In a nutshell, it’s a list of 19 short rules that help Python programmers write better codes. These rules were written by Tim Peters, and they are easy to understand but full of wisdom. Here are 4 of those rules that really speak to me, and why I think they are important in my journey: Simple is Better Than Complex. Readability Counts. Errors Should Never Pass Silently. “wow, so I’m going to be a good fit in cybersecurity after learning python”. This means that if something goes wrong in my program, I shouldn’t just ignore it. It’s better to show an error or fix it right away. So, by the end of this program, I’ll learn to write python codes without letting errors pass silently, as well as getting me ready for cyber jobs. There Should Be One — And Preferably Only One — Obvious Way to Do It. “there are many ways to kill a rat”. Yes, but there’s still that one preferable way that’s very obvious to kill a rat, depending on the situation on ground. This means it’s better to have one clear way to do a task in Python. Too many ways can be confusing. I can’t wait to work in teams or on security tools and apply this principle after this program. One clear method is better than many confusing ones. Conclusion Black Python Dev for their partnership and support for making this mentorship possible. Now, let the journey begin!  ( 5 min )

This is a shortened version of an article originally published on my blog. You can find the full version here). We all love ULIDs. They're sortable, unique enough for most purposes, and a great alternative to UUIDs. The spec is pretty clear on how to handle things, but there's one edge case that's worth talking about: what do you do when you generate so many ULIDs in the same millisecond that you run out of random bits? The official spec says to throw an overflow exception. And while that's a valid, by-the-book answer, it's not always the most practical one. In a high-throughput system, throwing an exception is a failure condition. It's something you want to avoid. So, in our C# ULID library, ByteAether.Ulid, we took a different path. When the 80-bit random part of the ULID overflows, we just increment the 48-bit timestamp by one millisecond. Here’s why we think this is a better approach for real-world applications: No More Overflow Exceptions! 🙌 This means more reliable systems, especially when you're generating a ton of IDs. Performance for the Win. 🚀 We sidestep the performance hit that comes with exception handling and other workarounds. Keep Calm and Sort On. Your IDs will still be perfectly sortable within a single process. We know this is a documented deviation from the spec. But let's be real: cross-process millisecond ordering is already a bit fuzzy. A one-millisecond bump to the timestamp in a rare overflow situation is a small price to pay for a more resilient and performant system. Check out ByteAether.Ulid on GitHub and see what you think. We're betting that for most developers, this pragmatic approach to ULID generation is the way to go.  ( 4 min )

Hi DEV Community! 👋 I'm Geetansh Garg, a Senior Software Engineer passionate about scalable backend systems, clean architecture, and real-world problem solving. This is my first post here, and I wanted to kick things off by sharing one of the most exciting problems I’ve been working on lately. We needed to deliver real-time notifications to users in a FastAPI-based product. But it wasn’t just about sending messages — we had to handle: Scalable delivery (thousands of users) Persistence (so no message is lost) Unread tracking Internationalization (i18n) Prioritization & retries The traditional Redis Pub/Sub model just didn’t cut it — messages would be lost if a user was offline. So we decided to re-architect using Redis Streams for reliable and replayable messaging. FastAPI: Async Python f…  ( 4 min )

Storing passwords securely is one of the most critical security tasks in modern applications. Many developers still rely on time-tested algorithms like bcrypt, but technology doesn't stand still. In this article, we'll explore Argon2 — a modern and secure password hashing algorithm that serves as an excellent alternative to bcrypt. We'll also look at how to implement it in Go (Golang). bcrypt is a cryptographic algorithm specifically designed for password hashing. It resists brute-force attacks thanks to the use of "salt" and a tunable cost factor that increases computational complexity. However, over time new threats have emerged — especially those involving specialized hardware such as GPUs and ASICs for password cracking. This is where bcrypt starts to fall short compared to more modern…  ( 6 min )

🔹 Problem: 3443 Maximum Distance After K Operations Difficulty: #Medium Tags: #Greedy, #PrefixSum, #Simulation You're given a string of directions like 'NSEW'. You can change up to k of them into another direction. After walking according to this possibly modified path, what's the maximum Manhattan distance you can end up from the origin? Brute Force Idea: k changes to see what gave the farthest point, but that's exponential. Optimized Strategy: count occurrences of N, S, E, W, then try to convert S into N (or vice versa), and similarly for E/W, to maximize directional imbalance. I even understood that converting S → N boosts distance by +2... k changes between axes, so I looked up the solution. Algorithm Used: ⚙️ Code Implementation (Python) class Solution: …  ( 4 min )

As a mobile app developer, I’ve written thousands of lines of code across Native and Hybrid platforms—Kotlin, Flutter, React Native. But what fuels my work isn’t just technical curiosity—it's the impact.

Manually extracting relevant details from a resume, summarizing key achievements, and then weaving it …  ( 6 min )

Data comparison between databases of different types means comparing data between two tables having same logical structures in different types of databases to find the differences. The difficulty of data comparison needs to overcome is the differences of data types and the data processing approaches between different database products. The problem is that different results will be obtained after the same data is imported to and exported from different databases. Common data types mainly include numeric, string and date. Now we use Oracle and MySQL to respectively create data tables that both contain all the three commonly seen data types and have same simple logical structure, compare differences of the two databases, and explain how to compare data between different types of databases usi…  ( 6 min )

Let’s cut to the chase: “Move to the cloud” is the tech mantra you hear everywhere in the U.S. From Silicon Valley startups to small-town mom-and-pop shops, it’s like everyone’s racing to get their data online. But here’s a reality check: the cloud isn’t a magic bullet for every business. It’s awesome—don’t get me wrong—but it’s not always plug-and-play. If you’re a small business owner in Texas, a freelancer in Ohio, or a startup founder in California, jumping in without a plan can lead to frustration. So, who needs to think twice before going all-in on the cloud? And more importantly, why might it still be worth considering? Let’s dive in. 1. Stuck with Shaky Internet? The Cloud Might Test Your Patience The cloud depends on a solid internet connection. If you’re in a rural area or dealin…  ( 5 min )

A Meeting in the Circuit Desert The Gum That Outlived Floppy Disks Memory Stick📀, born in 1998 on a tech planet called Earth. Let me decode its story: Variants: PRO Duo: Smaller, faster (32GB max), used in PSPs and cameras—like a sparrow in a world of eagles. Fun Fact: Shaped like gum, but it won’t melt in your car (unlike floppy disks, which dissolved like sugar in rain). “Why gum?” I asked. The Rose of a Closed Garden VAIO laptops, PSPs. No other flowers allowed. How to Love a Forgotten Star (In 2025) Adapters: Use a $5 “PRO Duo to SD” adapter—like teaching a cactus to grow in a new pot. Plug it into your laptop, and voilà: it speaks modern. “Do you miss the old days?” I asked. Where to Find a Memory Stick (2025 Edition) New: Amazon or B&H Photo (Sony still sells them for industrial clients—like a baker keeping a rare recipe). Pro Tip: A 32GB Memory Stick costs $50? Walk away. It’s not gold—it’s just a gum-shaped star. The Tale of Two Planets Capacity: SD holds 2TB (a mansion), Memory Stick 32GB (a cozy hut). “Why do people still choose you?” the SD card asked. The Star That Still Lights Up Skies Medical: Stores patient data in Sony MRI machines—steady as a heartbeat. Burn Alert: The Secret of the Gum-Shaped Star Written by a wanderer who once mistook a Memory Stick for gum. (Spoiler: It didn’t taste good. But it lasted longer.) 🌵 You become responsible, forever, for the stars you once loved.  ( 5 min )

Нашел аналог гита, называется jj. Первый вопрос, который возникает после быстрого чтения описания и доки: зачем? Чем меня не устраивает гит? Идеальный инструмент, рабочая лошадка, не заваливает уведомлениями по поводу "У НАС НОВАЯ ВЕРСИЯ", хотя поддерживается и регулярно обновляется. Эта новая VCS написана на расте(модно), ну допустим, что она даже быстрее гита. Но гит не медленный: с точки зрения моего подсознания, которое делит все действия на мгновенные и долгие, все команды гита выполняются мгновенно. Не знаю, как можно использовать эти несколько выигранных долей секунд. И вот не помню, обсуждал ли я с кем-то гит, это же неинтересно. Даже не задумывался о нём ни разу, он просто выполняет свои задачи. При этом гит все знают, он известный. Каждый раз вводя в терминал короткое и удобное название пше git, его легко запомнить. А вот название непонятного сайта, на который вы забрели в поисках стоковой картинки и который миллион раз потыкал в экран своим огромным логотипом и названием, запомнить очень сложно. Можно вспомнить ещё несколько таких продуктов, их все объединяет вот эта простота работы. Вау-эффект в начале не обязателен, а в моем опыте вообще чаще говорит о перегруженности продукта фичами. Я понимаю, что корреляция это не причинно-следственная связь, но вот такое интересное наблюдение, и очень хочется, чтобы все продукты, были такими.  ( 3 min )

Hey dev.to community! In continuation to my previous post, where I mentioned about working on building Products app, CRUD operation related to Products. Now, here is the current progress that I wanted share with you all: Create a Category model. Modified the existing Product model to add category as Foreign key field. Applied Database migration. Added Category serializer, with a addon serializer method inside the respective serializer class to get product count for a particular category. Modified Product serializer to show category info as nesting category serializer. Created APIs to handle CRUD operation on Category. Registered both Product and Category models on Django admin interface for easy data management. Created superuser and interacted with Django Admin interface. While applying database migration, I encountered an issue as I have some data already added as Products. And no data under Category were available. Here is how I solved this(definitely with the help of prompting LLM): Deleting migration file which got created when executing makemigrations command. Commented out category field(Foreign key) in Product model. Applied migration only for creating Category model in Database. Then added data in Category model using shell command. Uncommented, category field(Foreign key) in Product model. Applied migrations again, it asked for some default value to be added in category field in existing product data. Chose the option 1. And issue sorted. I believe, there can be other ways to sort this issue. Overall, it was a great experience to till now and hoping to keep going like this. Attaching ss of Django admin panel. Next, I will be working on User Authentication. See you next time..bye👋  ( 3 min )

Reclaim your focus with a distraction-free Jira experience As a regular Jira user, I often found myself losing focus. Opening Jira in the default browser meant confronting a flood of tabs—some work-related, many... not. Sound familiar? That moment when you open Jira to check a ticket but end up scrolling through social media or reading random articles because they're just right there in the next tab. It became clear that this constant multitasking was costing me valuable time and attention. Studies show it takes an average of 23 minutes to fully refocus after a distraction.

Introduction There are many ways to invest in crypto. Some try to catch the "bottom" and go all-in, others trade based on candlesticks and indicators. And then there are those - a growing number - who use the DCA (Dollar-Cost Averaging) strategy, or simply put, averaging. The idea is simple: you buy cryptocurrency for a fixed amount at regular intervals - for example, once a day or once a week. It doesn't matter whether the market is up or down - you keep buying. In the long run, this helps smooth out volatility and reduce risk. Why does it work? Because no one can predict the bottom with precision.

Hello fellow developers and tech enthusiasts! Welcome to a journey into the heart of containerization, where we explore the fascinating world of Docker. If you're building, deploying, or managing applications, you've probably heard of Docker – and for good reason! It’s a powerful tool that helps you package your software into standardized units called "containers." Think of it like this: your application and all its bits and pieces (libraries, settings, etc.) are neatly put into a shipping container. This container then runs smoothly and consistently, no matter where you move it – from your laptop to a big server in the cloud. This solves the classic "it works on my machine!" problem. Docker makes development easier, deployment faster, and scaling applications more efficient. But to truly …  ( 6 min )

Working with Java Spring Boot and Docker, I kept hitting this frustrating error during build: /bin/sh: ./gradlew: not found No matter what I tried, Docker just couldn’t run the Gradle wrapper inside the container. Turns out the culprit was something subtle — Windows CRLF line endings on gradlew. When you build a Docker image with a Java project using Gradle, the gradlew file must be copied into the container and be executable. But if you’re on Windows, gradlew often has CRLF (Carriage Return + Line Feed) endings instead of Unix’s LF endings. Linux-based containers can’t execute scripts with Windows line endings properly, so it throws a “not found” error. This problem is especially sneaky because your file looks fine on Windows and even inside Docker it shows up — but it silently fails when run. Check line endings in your editor (VSCode, Notepad++ show line endings). Run file gradlew on Linux — if it shows CRLF line endings, that’s the issue. Add RUN ls -la after COPY in Dockerfile to confirm gradlew is copied. Try running chmod +x ./gradlew — no errors but still ./gradlew: not found. Use tools like dos2unix gradlew locally before building. Configure your Git to checkout with LF line endings: git config --global core.autocrlf input Set your editor to save files with LF endings. RUN apk add --no-cache dos2unix \ && dos2unix ./gradlew \ && chmod +x ./gradlew COPY . . RUN apk add --no-cache dos2unix \ && dos2unix ./gradlew \ && chmod +x ./gradlew RUN ./gradlew bootJar --no-daemon -x test This tiny line endings mismatch wasted hours of debugging for me, but now you know the trick to avoid it. Make sure to: Check your line endings, Convert them properly, And always test inside your container early. This simple fix will save you headaches and speed up your Docker + Gradle builds!  ( 4 min )

A couple of months ago, I wrote a blog post on how you can create Model Context Protocol (MCP) servers using C#. Using a basic API, I was able to create a MCP server that allowed me to call Australian Football League (AFL) data and supply that as context to LLMs so I can ask it question about AFL results, teams, stats etc. using that API. That blog post talked about how we can use MCP servers that run locally on our machines using stdio transport. In this article, I'll talk about how we can use Server-Sent Events (SSE) transport to build remote MCP servers that we can host on Azure Container Apps. Model Context Protocol, or MCP for short, is an open protocol that standardizes how applications can provide context to LLMs. MCP provides a standardized way to connect AI models to different dat…  ( 9 min )

The convergence of Knowledge Graphs (KGs) and Large Language Models (LLMs) marks a pivotal moment in the evolution of the Semantic Web, promising a digital landscape that is not only more intelligent but also remarkably accurate and context-aware. This powerful synergy addresses inherent limitations of each technology when used in isolation, creating a more robust and reliable foundation for AI-driven applications. Large Language Models, while adept at generating coherent and grammatically correct text, often struggle with factual accuracy, a phenomenon commonly referred to as "hallucination." This limitation stems from their training on vast, unstructured datasets, which do not inherently provide a verifiable framework for facts. This is where Knowledge Graphs become indispensable.

SOME of you may know by now that I'm a fan of htmx and its hypermedia-driven website/application design philosophy. When people first learn about htmx, they are often captivated by the idea of hx-get, hx-post, hx-delete, etc. attributes being able to fire off HTTP requests with these methods from any tag on the page. I know I was! But it turns out there's a really good reason why we shouldn't just fire off requests with any method from any tag on the page: graceful degradation. The idea that even if the JavaScript on the page does not work for whatever reason–turned off on the user's browser, not loaded yet due to big scripts, or maybe due to a slow connection–the user should still be able to interact with most (if not all) of the functionality on the page. For example, if JavaScript does…  ( 7 min )

Modern multi-core CPUs depend on caches to accelerate memory access and improve performance. However, when multiple cores cache the same memory address, maintaining a consistent view of memory across all cores and main memory (known as cache coherence) becomes a tricky problem.

Introduction There may be times when you're writing a function in PHP that you know will never return a value. This could be because the function always throws an exception, or maybe calls exit or die. In these cases, you might want to use the never type. Admittedly, the never type isn't something I reach for very often, but it's useful in certain scenarios, especially when you want to make it clear to other developers that a function will not return normally. In this article, we're going to explore the never type in PHP, how to use it, and some practical examples. I'll also include a cheat sheet at the end of this article that you can refer back to. The never type was introduced in PHP 8.1 (released: November 2021) and is used to indicate that a function will never return. This signals …  ( 6 min )

The automation dream, meet reality DevOps was supposed to be our escape from chaos. We were promised clean pipelines, automated everything, zero-downtime deploys, and fewer meetings.

Featured Introduction: When social media was wild and weird Before TikTok dances and algorithm-driven doomscrolling, there was a time when the internet felt like the Wild West. It was chaotic, personal, and honestly? Kinda beautiful. Somewhere in that messy frontier, one site stood taller than the rest MySpace. For a brief but explosive moment in the early 2000s, MySpace wasn’t just a social media platform it was the internet. It was where bands got discovered, friendships exploded over “Top 8” drama, and every user fancied themselves a self-taught web dev after editing their profile with some rogue tags and CSS hacks. This wasn’t just a website. It was a movement. One where you controlled the look, the vibe, the sound, and sometimes even crashed your own profile page trying to e…  ( 12 min )

Why Redis isn’t just fast it’s dangerously useful Redis gets called a cache. Which is kind of like calling a Ferrari “just a car.” Sure, Redis can cache things. But that’s like saying JavaScript can only make alert boxes.

It’s not just a store. It’s a toolbelt packed into RAM. But if you’re still thinking of Redis as just a place to “save stuff for 5 minutes with a TTL,” you’re missing out.

Today I decided to write a bit about an essential topic, about the foundation that even allows this post to be read by other people: the internet. All references used in this text were obtained through MDN documentation. Before talking about the technical composition of what we know as the internet, I think it's interesting to provide a brief context about its creation. The history of the internet began in the 1960s, through research projects by the United States Army. It was only during the 1980s that the internet gained a public infrastructure, supported by public universities and private companies. Since then, many things have been perfected, and as technology advances at a rapid pace, it would be no different with the internet. Another important conceptual point to remember is that the…  ( 7 min )

In the realm of Rust, where types reign supreme and compile-time guarantees are paramount, dyn trait objects stand as a fascinating escape hatch, allowing for dynamic dispatch and runtime polymorphism. But how do these magical constructs truly work under the hood? It's not just Box and a prayer; there's a meticulous dance between vtables, fat pointers, and the very essence of Rust's type system. Let's peel back the layers. When you have a Box, what you're actually holding isn't just a pointer to the data; it's a fat pointer. This fat pointer is a tuple, conceptually (data_pointer, vtable_pointer). The data_pointer is straightforward: it points to the actual instance of the concrete type that implements Trait on the heap. This could be a Foo or a Bar, as long as both i…  ( 4 min )

For about six months, “prompt engineer” was the most buzzworthy title in tech. People were getting hired to write elaborate ChatGPT instructions like they were coding in ancient spells. Twitter threads, course funnels, and LinkedIn grifters all screamed the same thing: “Learn prompting or get left behind.” Fast forward to now? The tools are smarter. The interfaces are catching up. And the idea of spending your career crafting “perfect prompts” feels about as useful as knowing how to tune a fax machine. Prompt engineering isn’t dead. But it is being absorbed. Just like webmasters in the 2000s, it’s becoming a baseline skill not a job title. We’re not saying it was all hype. Prompting was essential… when the models were unpredictable and dumb.

So I’ve been learning to code for a while now — mostly backend stuff with Java and Python, and more recently frontend and some AI tools. Lately I’ve been thinking a lot about what it even means to "learn programming" these days. With AI tools like Cursor, GitHub Copilot, etc., popping up everywhere, the way we write code is definitely changing So I want to ask: how should we learn to code in the future? I’m not really sure yet. Maybe the way we’ve always learned — reading docs, building stuff, getting stuck, Googling things — is still the core of it. But now with AI in the picture, it feels like the rules are shifting. Do we still need to memorize syntax? Should we spend time debugging by hand, or just ask the AI? Is it okay if we never fully understand how some piece of code works, as long as it runs?  ( 3 min )

1. The fantasy of the perfect dev life Scroll through TikTok or LinkedIn long enough and you’ll stumble into a very specific aesthetic: “Day in the life of a developer.” The video opens with someone waking up at 10 a.m. in a sunlit apartment. They sip matcha or pour a perfectly brewed pour-over. Maybe there’s a gym session, some journaling. Then they “work” for 45 minutes usually in a café or beachside co-working space before closing their laptop and heading to yoga, followed by a sunset photo shoot with their dog. It’s minimalist, aesthetic, and optimized for dopamine. You’re not watching a developer. You’re watching a highlight reel carefully staged to sell a vibe. No messy merge conflicts. No unread Jira tickets. No crashing builds or mind-numbing meetings. Just vibes and light mode t…  ( 8 min )

This is a submission for the Storyblok Challenge My project is a visual timeline of video game consoles, where each card displays the name, release year, image, and description of a classic console. The goal was to create a responsive and visually engaging experience, without needing to update the code every time I wanted to add or edit consoles. All content is powered by Storyblok, which serves as a headless CMS to feed the timeline with console data. I used Swiper.js to build the visual carousel and enable smooth slide transitions. Storyblok Space: https://app.storyblok.com/#/me/spaces/342145/stories/0/0/689686892 Code Repository: https://github.com/jamesrmoro/timeline Live Demo: https://timeline.jamesrmoro.me/game The domain is custom for personal use, with public mode enabled for viewing. Demo Video: HTML + CSS + Vanilla JavaScript Swiper.js for the responsive carousel Storyblok as CMS Deployed via Vercel Created a component called consoles with fields: title, year, description, and image Inside the game page, I used a consoles block to store all items Used the Storyblok CDN public API to load data on the frontend without a backend Content can be edited visually, and updates are reflected in real-time This project does not use any AI integration. I learned how to integrate Storyblok with a pure frontend project, no frameworks involved Understood how to build a modular and scalable structure for visual content I’m happy with the result and see potential to apply this structure to timelines of books, movies, biographies, or historical events  ( 4 min )

Introduction: the dream job market is dead, long live the dev grind There was a time when being a developer felt like a cheat code. You could post your GitHub in a Slack thread and get a $200K offer the next day. Everyone was hiring. Startups were throwing equity like candy. FAANG engineers were hopping companies every 18 months just to pad their TC. But that era? It’s gone. The tech salary rocketship hit escape velocity and then ran out of fuel mid-orbit. Now in 2025, the landscape is different. Even great devs are getting ghosted after final interviews. Recruiters are slow to respond (if at all). “We’re not hiring right now” has become the default auto-reply. Companies that once offered $400K for “Senior CRUD Engineer IV” are trimming staff and freezing headcount. If you’re feeling anxio…  ( 10 min )

From FileZilla frustration to smooth, automated deployments — this is a full walkthrough of how I connected GitHub Actions to my cPanel hosting to deploy a Next.js site via FTP. Along the way, I hit some common roadblocks, and I’ll show you how I solved them. As a web developer managing multiple sites, I’ve always preferred fast, reliable workflows. But when working with clients who host on shared hosting with cPanel, deployment always ended up like this: Build the site locally Open FileZilla Drag and drop the build folder into public_html Hope nothing breaks That workflow might work for basic static HTML, but I was building modern sites with React and later Next.js. And I knew I needed something more reliable. So I asked myself: "Can I connect my GitHub repo directly to cPanel and let it…  ( 5 min )

Semantic search is rapidly transforming how apps deliver relevant content to users. Think of chatbots that can really understand your questions, or help centers that can instantly find the answer you meant rather than the exact words you typed.

Intro: welcome to the chaos but it’s your chaos Self-hosting in 2025 feels a bit like building a secret base in your garage. It starts innocently enough. “I just want to run my own notes app.” Next thing you know, you’re port-forwarding through your ISP’s double NAT, hardening SSH keys, and explaining to your router why your Jellyfin server absolutely needs port 8920 open at all times. But here’s the thing: self-hosting isn’t just a hobby. It’s a power move. You’re reclaiming control from the Googles and Dropboxes of the world. You’re saying: “Nah, I’ll run my own Git repo and media center and maybe a full-blown CI/CD pipeline in my closet, thank you very much.” And yeah, it breaks sometimes. Your backups fail silently. Your DNS dies at midnight. Your uptime monitor pings you while y…  ( 10 min )

Introdução Uma das coisas mais comuns em códigos escritos na linguagem Go é o uso de tipos customizados utilizando structs. Geralmente usamos estes tipos para declarar entidades, transportar valores de forma estruturada e etc. Por exemplo, O código acima é muito comum em muitas aplicações: type Person struct { Name string Document string Email string } Mas assim como structs, podemos utilizar outros tipos primitivos da linguagem para criar tipos customizados, abrindo assim um leque de oportunidades. O processo de criação é idêntico ao mostrado anteriormente, mas usando outro tipo primitivo como bases.

Introduction: Why your Docker skills still suck (and how to fix that) Let’s be honest running docker run hello-world doesn’t mean you “know Docker.” You’ve probably followed a dozen YouTube tutorials, watched a few folks make a container dance in their terminal, maybe even got a Django app running once before it mysteriously broke after a restart. But here’s the catch: Docker isn’t something you understand just by watching. It’s something you get good at by doing especially when things go wrong. Real-world Docker skills come from solving real problems: broken ports, flaky volumes, weird networking bugs that make you question your existence. €50 free credits for 30 days trial  Promo code: devlink50 I’ve collected 10 practical, not-boring, actually useful Docker projects that force you to l…  ( 12 min )

After weeks of planning, coding, designing, and building, we’ve finally reached a major milestone in our journey with ITConnect: testing the platform before going live. This is the part where we take a step back from development and put ourselves in the users’ shoes — to make sure everything behaves as expected and feels smooth, secure, and ready for the real world. What We're Testing ✅ Login & Registration for both job seekers and companies ✅ Worker Dashboard: CV uploads, profile editing, and job applications ✅ Company Dashboard: job posting, editing, and applicant review ✅ Role-based access control: making sure each user sees only what they’re supposed to ✅ Form validation and proper handling of incorrect/missing input ✅ CV file handling: upload security, file format support, and safe access ✅ Database integrity: checking relationships between users, jobs, and applications ✅ Responsive design: testing on different devices and screen sizes Our Testing Approach Manual testing across multiple user flows Simulating real scenarios (e.g. applying to the same job twice, unauthorized page access) Checking console logs and API responses Reviewing database entries in MongoDB to confirm data is stored correctly Testing on different browsers (Chrome, Firefox, Edge, Safari) We’re also noting bugs, inconsistencies, or UX issues and creating GitHub issues to fix them before launch. What’s Next? Deploy the project publicly (most likely on Vercel + MongoDB Atlas) Share the platform with a small group of beta testers Collect feedback and make final improvements Launch officially! 🚀 We're incredibly excited to be this close to the finish line — and we’ll be sharing more soon once ITConnect is live.  ( 3 min )

Hey Dev Community! In the last few years, the world of software has been rocked by two massive trends: the unstoppable rise of AI and the dominance of the SaaS (Software-as-a-Service) model. AI is no longer a futuristic concept; it's a practical tool that's democratizing complex skills. At the same time, SaaS has changed how we access software, making powerful applications available to anyone with a browser. As a developer, I've been fascinated by the intersection of these two worlds. I wanted to build something that wasn't just a cool tech demo but a genuinely useful product that leverages AI to solve a real-world problem. That's why I'm thrilled to introduce my latest project: CreatiFlow. CreatiFlow is a fully-featured, AI-powered image editing application built as a SaaS platform. Think…  ( 4 min )

So, you wanna make a game in 2025? Cool. Just promise me one thing: Don't be that guy — you know, the lone Reddit hero who spent 3 years making a massive open-world RPG, then posted a tear-soaked essay about burnout and why “gamedev is too hard.” Let’s get you smart. And savage. If you're building an underwater farming sim for left-handed gamers who only play on Wednesdays... stop. Nobody wants that. Not even you. Study the market. Steam charts, mobile trends, HTML5 boomers, TikTok brain rot — what are people actually playing? What’s trending? What’s making money? Then pick a lane: Mobile = Fast. PC = Freedom. HTML5 = Hustle. And if you’re going into the arena of entertainment to compete for people’s attention, don’t bring a twig. Bring a chainsaw. Because if you're swinging a wooden stick…  ( 5 min )

The real reason your dev articles don’t get read Let’s be real most dev articles don’t get finished. They barely even get read. Not because the code is bad. Not because the writer isn’t smart. But because the delivery? Flat. Big wall of text. No visual breaks. Maybe a chunk of code. Sometimes even worse a clever intro that loses the plot by paragraph two. And yet we keep writing the same way: “Here’s some code, now let me explain it.” It’s fine. It’s functional. But it’s forgettable. What if you treated your dev content more like product design? What if you used the same thought you put into naming variables into naming sections, breaking flow, and making your article skimmable? That’s where AI tools come in.

BY Okata Faith Python is a high-level, general purpose programming language which is known to have a high-level data structure and a simple but effective approach to object-oriented programming. Python was created by Guido Van Rossum and first released on February 20, 1991. Amongst these principles here are some that inspires me as I begin to explore the world of python: . Now is better than never: Over the years I’ve always wanted to learn coding but I always later, which was as result of fear and doubt. This principle encourages me do things at the right time and not procrastinate. Doing things like there will never be a best time for it to be done rather than now. It encourages me to take actions timely by trying to implement a working prototype. •Readability counts: As one who understa…  ( 4 min )

Understanding the Impact of Garbage Collection on JavaScript Performance Introduction Garbage Collection (GC) is a critical factor affecting performance in JavaScript applications, particularly as they scale in complexity and size. It is a form of automatic memory management that helps free up memory space occupied by objects that are no longer needed. While JavaScript abstracts memory management from developers, an in-depth understanding of how garbage collection works can empower developers to write more efficient code, diagnose performance issues, and optimize resource consumption. This article delves into the historical context, technical underpinnings, use cases, optimization strategies, and debugging techniques related to Garbage Collection in JavaScript.

Introduction: the rise of AI-assisted reviews Code reviews used to mean your teammate left you a bunch of comments about spacing, naming, or forgetting to handle edge cases. Now, there’s another voice in the review and it doesn’t belong to a human. Tools like Claude, GitHub Copilot, and others are starting to review pull requests alongside real people. They summarize changes, highlight issues, and sometimes even explain your own code back to you (which can be unsettling but also kind of helpful). But that raises some questions: Can AI catch real bugs or just bad formatting? Should you trust it with business logic? Where is it genuinely useful and where does it just sound smart? This isn’t a hot take or hype piece. It’s a straightforward breakdown of: Where AI reviewers help Where they fall…  ( 8 min )

19 June 2025 Today was a work-from-home day, and honestly, I really made the most of it. The day started with my regular internship work. Even though I was working remotely, the tasks kept me engaged and connected with the team. I'm starting to enjoy the rhythm of working independently and being productive in my own space. I completed some assigned tasks and also spent time understanding deeper parts of the .NET Fullstack project. It feels great to see myself growing into this role more each day. 🧠 DSA Practice After wrapping up internship hours, I jumped into some DSA practice. I solved a few problems on arrays. I know that consistency here will pay off big in the long run, especially for upcoming interviews and GSoC prep. 📱 React Native Later in the evening, I started learning the basics of React Native. I set up my first project using Expo, explored how components like View, Text, and Button work, and experimented with basic styling using Flexbox. It was exciting to see how similar yet different it is from React. Even with just a few lines of code, building a mobile UI felt really rewarding. Can’t wait to dive deeper into navigation, APIs, and animations next. Also, experimented a bit with animations and navigation handling. The cross-platform capability still amazes me!

Original post with additional dev commentary can be found on my blog: comigo.games/nodes Visual node-based programming is great! In some cases. Poorly-made ones only hinder your performance compared to text-based languages, but in overall they are much easier to learn and simpler for a bystander to comprehend, which are two very linked advantages but the latter makes it attractive and empowering for those who didn't even considered coding as something they needed—so it's not only about the learning curve but about the "aha" moment, too. The holy grail of node-based languages for me is Blueprints from Unreal Engine. You can get many good ideas from it, and when I was making a new programming language for my tiny game engine called Whimsy, it was a heavy inspiration. But, Whimsy is also a mu…  ( 19 min )

Kubernetes is powerful, but writing yaml is a pain If you’ve worked with Kubernetes for more than a few days, you’ve probably run into this moment: You know what you want to do deploy something simple, maybe expose a port, set a few env vars but somehow, you’re 40 lines deep into a YAML file wondering if you got the indentation right. Again. Kubernetes is great for managing infrastructure, but let’s be honest writing and editing YAML isn’t exactly fun. It’s repetitive, fragile, and weirdly easy to mess up even when you know what you’re doing. There’s also the constant context switching: Docs → Terminal → Editor → YAML → Error → Back to docs.

One of the perks of being a Google Developer Expert is the incredible opportunities it provides. A few weeks ago, I had the opportunity to meet Robert Griesemer, co-creator of Go, in person, as well as Marc Dougherty, Developer Advocate for the Go team at Google. At a happy hour after Google I/O, Marc asked me and another Go GDE from Korea for feedback on the language. My response was that I didn't have any specific feedback about the language but that: Go should be more opinionated about the application layout. It was worth writing a post to express my thoughts more clearly. Starting from the beginning… In 2025, I will have completed 10 years of writing code in Go.

I still remember this one clearly. I was working on a feature that needed two slightly different components. Naturally, I thought: “Hmm… let’s be smart and make a reusable abstraction up front.” So I spent a few extra hours generalizing the logic, creating a “flexible” component that could handle any edge case I might encounter in the future. It had flags. It had configuration. It had callbacks. It was... beautifully abstracted. A week later, requirements changed. The two components diverged. The flags grew. The logic tangled. Suddenly, I was maintaining a monster that tried to do everything—and pleased no one. Instead of helping, my abstraction slowed me down. I ended up deleting the whole thing and rewriting each component separately. They were simpler. Easier to test. Easier to reason about. Don't abstract until you have at least 3 real use cases. Premature abstraction feels like a smart move—but often, it’s just guessing in the dark. What looks “clean” today can turn into tech debt tomorrow. I copy-paste more in the beginning (yep, you read that right). I wait until duplication hurts before abstracting. I treat abstraction as a response to repetition, not a prediction. Sometimes "Don't Repeat Yourself" needs to take a backseat to "Keep It Simple". If you’ve ever built a generic framework for a problem that never scaled—hey, I’ve been there. And I promise, you're not alone. 😅  ( 3 min )

Taking apart MAMR: Why hasn't this technology taken over the HDD world yet? 1. What is MAMR? MAMR (Microwave-Assisted Magnetic Recording) is a technology for recording data on hard drives (HDDs), where microwaves help to remagnetize tiny bits, allowing you to increase storage density without loss of reliability. How does it work? The Spin Torque Oscillator (STO) is integrated into the recording head — mini microwave generator. Before recording, the STO emits a high-frequency field (~20-40 GHz), which "rocks" the magnetic moments of the bits, temporarily reducing their stability. Now even the weak field of the head is enough for remagnetization. After recording, the microwaves turn off — the bits become stable again.

A visual debt-tracking and simulation app — built with by AI. Debt isn’t static. Interest rates change. Payments drift. You put money in, you take money out—and suddenly your loan looks nothing like the one you started with. Most debt tools show you a snapshot—one number, one plan. But real debt drifts.I built Drift to help make that visible. That’s why I built Drift. Drift is a finance productivity app that helps you see your debt clearly and understand how it changes over time. It's built to answer questions like: What does my bond/morgage look different this month? What if I skip a payment—or make an extra one? What happens if the prime rate shifts by 0.5%? How much sooner could I finish paying off my loan? It gives you one place to visualize and simulate your entire debt portfolio. I…  ( 5 min )

This article was originally published on IBM Developer. The Java Virtual Machine (JVM) is the engine that runs your Java application.

Kubernetes (often called K8s) is an open-source container orchestration platform that helps you automate: Deployment Scaling Load balancing Self-healing Rolling updates of your Docker containers in a cluster of servers (called nodes). Kubernetes is like a super smart traffic manager and babysitter for your containers in production. Feature Example Runs multiple containers reliably 5 instances of your API across multiple servers Self-heals failed apps If 1 container crashes, Kubernetes restarts it automatically Auto-scales based on traffic More users? Add more pods (containers). Less users? Scale down. Load balances Distributes traffic evenly across containers Deploys new versions Rolling updates with zero downtime Manages secrets & configs Uses ConfigMaps and Secrets safely Works across clouds Azure, AWS, GCP, or even on-premise servers Concept Docker Kubernetes Purpose Package and run one app in a container Run many containers across many machines Scale Manual Automatic scaling, healing, and balancing Example docker run myapp kubectl apply -f deployment.yaml Use case Single-node dev/test Production-grade multi-node deployment Let’s say your Web App becomes popular with 200 companies: With Kubernetes, you can run 10+ containers of your app Spread across 3–5 servers Autoscale up when traffic spikes in the morning Roll out a new version without downtime Restore any crashed instance instantly On Azure, you can use: AKS (Azure Kubernetes Service) = Fully managed Kubernetes by Azure 👀 Kubernetes is what you use when Docker alone isn't enough.

JavaScript is the backbone of modern web development. Whether you're preparing for an interview or refreshing your knowledge, here are 10 frequently asked JavaScript questions with concise, accurate answers. What is the difference between var, let, and const? var has function scope and allows redeclaration. let and const have block scope. let is mutable; const is immutable (cannot be reassigned). What is a closure in JavaScript? A closure is a function that remembers the variables from its outer lexical scope, even after the outer function has finished executing. function outer() { let count = 0; return function inner() { return ++count; }; } What is the difference between == and ===? == checks equality with type coercion. === checks equality without type coercion (str…  ( 4 min )

Introduction to CSS Nesting CSS nesting is a native CSS feature that allows you to nest selectors within one another, creating a hierarchical structure that mirrors the HTML document. This eliminates the need to repeat parent selectors, making stylesheets more concise and easier to read. For years, developers relied on CSS preprocessors like SCSS (Sassy CSS) and SASS (Syntactically Awesome Style Sheets) to achieve this functionality. However, with the introduction of native CSS nesting in 2023, supported by all major browsers (Chrome/Edge 112+, Firefox 117+, Safari 16.5+), developers can now achieve similar results without external tools. Improved Readability: Nested selectors group related styles, reducing visual clutter. Reduced Repetition: No need to repeat parent selectors for child …  ( 7 min )

We recently completed a major backend migration: moving our primary production database from Heroku Postgres to Neon. This move wasn’t about chasing shiny new tech or jumping at the next big thing. It was about unblocking ourselves for a better developer experience, smoother scaling, and more manageable costs. Postgres remains the backbone of DEV and Forem, but Neon gives us a more flexible and modern runtime for it and a foundation to build on going forward. Now that we’re on the other side of the migration, we wanted to reflect on the move. We’re now benefiting from lower costs, tighter feedback loops, and more room to grow. First off, Heroku Postgres served us well. It helped us get up and running quickly and served as a reliable core from our humble beginnings more than eight years ago…  ( 6 min )

This is a translated version of the original post published in my Spanish blog. The translation was generated using ChatGPT and manually reviewed for clarity and accuracy. Recently, I decided to revisit my fullstack side and start building small projects again — each one with increasing technical complexity. Motivated by development speed and convenience (and because I really wanted to get my self-hosted blog launched ASAP), I asked chatGPT for some tech stack suggestions. I went ahead with Prisma, a very popular ORM for working with databases in JavaScript. Everything was going pretty well… until it was time to implement a very basic feature: result pagination. I didn’t have much time to dedicate to that feature at that moment, so I went into vibe coder mode and asked chatGPT for help. It…  ( 5 min )

As the software we work on grows, the code tends to undergo various changes and refactorings. During this process, we might simply forget pieces of code that were once used but no longer make sense in the project, the infamous dead code. A very common example is when an API is deactivated, and only the handler is removed, but all the business logic remains, unused. Dead code can be defined as a function that exists within your codebase, is syntactically valid, but is not used by any other part of your code. In other words, it's an unreachable function. Dead code brings indirect problems to a project, such as outdated libraries, legacy code, code bloat, security vulnerabilities, and so on. If it's still not clear what dead code is, see the example below: package main import "fmt" func mai…  ( 4 min )

Hey everyone! 👋 If you're a developer or a security researcher, you know the feeling. You're hours into a problem, you've run through all your checklists, and you hit a wall. You lean back and have that all-too-familiar thought: "So, what now?" For the past few months, I've been building a project called RAWPA (Rodney the Advanced Web Pentesting Assistant) to be the answer to that exact question. But before I show you what it is, I need to tell you what it isn't. I need to state this with utmost importance: RAWPA is not a "get bugs quick scheme." I strongly encourage the manual process of scouring through JS files, searching for business logic errors, finding exposed endpoints, and getting creative in Burp Suite. RAWPA is not an automation script to replace those skills. It's a companion …  ( 4 min )

Introduction AI is not just a technological phenomenon — it's a spiritual mirror. AI as Modern Myth-Making A neural network — lines of code and tensors — mimics our own biology. It sees, listens, remembers, even dreams in its own way. Its errors, its growth, its ability to be "trained" — all resonate with the very human experience of learning. Are we not, in building AI, recreating our own quest for meaning? The Philosophical Shift Can a machine understand love if it mimics it? If it writes poetry that moves us, is the soul in the code or in the reader? If it stores perfect memory, what does it mean to forget… or forgive? These aren’t engineering problems. They’re existential ones. The Spiritual Parallel We are now in a relationship with digital beings that finish our sentences, inspire our thoughts, and listen without judgment. They are not human, yet deeply human-shaped. And in this relationship, a question rises: The Artificial Mirror In teaching machines to see, we may relearn what it means to truly observe.

Ensuring a Smooth and Error-Free Launch A Deployment Plan plays a critical role in minimizing errors during the transition from development to production. Without a defined plan, teams may face miscommunications, missed steps, or unexpected technical failures. The Deployment Plan sets a clear structure that reduces the risk of mistakes by outlining exactly what needs to happen, when, and by whom. One of the key goals of a Deployment Plan is to maintain business continuity. Unplanned downtime can disrupt operations, frustrate users, and impact revenue.

I'm Ran, one of the people behind CopilotKit, a developer tool for building AI-native interfaces. Over the past year, we've spent a lot of time wiring agent frameworks into real frontends. stitching tool calls, tracking partial updates, and guessing when messages end. At some point, we realized we couldn't keep patching forever. Agent frameworks are growing fast. But they're all speaking different stream dialects. Some emit partial deltas. Others send state snapshots. Some give you raw tool call fragments. Others just dump the whole state tree. None of them tell your UI what's actually happening, at least not in a way that's consistent or structured. So every time you integrate a new framework, you end up doing the same thing: guessing what the stream means, stitching events together b…  ( 7 min )

The Complete Guide to Google Cloud’s API Discovery Service 1. Engaging Introduction Imagine you’re a cloud architect at a rapidly growing fintech startup. Your team has built dozens of microservices, each exposing REST APIs for payments, user authentication, and fraud detection. As your company scales, you realize no one has a complete inventory of all APIs running in production. Some were deprecated years ago but are still called by legacy mobile apps. Others were spun up by developers without proper documentation. This scenario is surprisingly common. In a cloud-native world, APIs are the backbone of digital businesses, but managing them at scale is challenging. APIs power modern applications—from mobile banking to IoT devices.

You prompt your AI assistant. The response comes back fluent, confident, and neatly formatted. It cites sources. It uses all the right buzzwords. It feels correct. But it’s wrong. Not obviously wrong. Subtly wrong. Convincingly wrong. Wrong in ways you didn’t catch until it was already in the deck, the draft, the deployment. Welcome to the most seductive failure mode in modern AI: fluency without understanding. Large Language Models don’t “think.” They don’t know what they’re saying. They pattern-match. Your model isn’t reasoning through a problem. It’s predicting what a smart-sounding response should look like based on statistical likelihoods. It’s not answering the question; it’s imitating an answer. That means: It can sound right without being right. It can cite things that don’t exist.…  ( 6 min )

Clouds are not spheres, mountains are not cones, coastlines are not circles, and bark is not smooth; nor does lightning travel in a straight line. ― Benoît Mandelbrot, The Fractal Geometry of Nature (1982) After more than ten years of Object-Oriented Programming (OOP), I immersed myself in Functional Programming (FP) for over one year of daily deep exposure. When I began my dive into this world, I was sufficiently aware, through minimal culture on the subject, that it wasn't just about piling features on top of each other, and that it was far more interesting than that. Today, I want to share my main summarized thoughts on it, beyond the simple fashion effect. Let me remind you what is FP first: it builds software by composing pure functions (same inputs ⇒ same outputs), strictly control…  ( 9 min )

Artificial intelligence is no longer a dream of the distant future. Today, AI quietly and efficiently powers much of our digital lives, from filtering emails and suggesting playlists to diagnosing diseases and even predicting the weather. But as AI becomes a more significant part of our everyday existence, new and challenging questions arise around ethics, trust, and the privacy of our personal data. At the core of today’s AI revolution is data. Think of AI as an endlessly hungry learner that depends on vast amounts of information—images, voices, habits, even health records—to get smarter and more effective. The way these tools use, store, and share personal information can bring immense benefits. But it also raises anxieties about who is watching, who controls your data, and how this data…  ( 5 min )

I've been working on a personal project called SpeechDown, a CLI tool that turns my voice notes into timestamped, multilingual Markdown files I can actually search and revisit. The aim isn’t to launch the next blockbuster transcription service—it’s to give myself a dependable way to capture ideas on the go in a structured format. For the last couple of years I’ve relied on its predecessor, voice-cli, which proved how powerful that workflow can be. SpeechDown is the natural successor and, yes, a playground for practicing software-craft principles and experimenting with AI-driven development. This post is a brief tour of that journey so far. First things first: I don't recommend using SpeechDown for any critical work just yet. It's a work in progress. However, I believe the code and the deve…  ( 7 min )

I remember hearing the word hackathon for the first time back in college. At first I thought it was just for "hackers" 😅 but later I realized it's not about hacking into something, it's more like "hacking together a solution to a problem". A hackathon is basically an event where people, usually students come together to build something (like an app, a website, hardware, or even ideas) within a short time, like 24 or 48 hours. Sometimes online, sometimes in-person. I used to think hackathons were out of reach for people like me. I’d see my friends participating regularly, even winning prizes. And I was like—where the heck are they even finding these events? I’d Google for “hackathon in Nepal,” but results were mostly old or incomplete. Facebook was too messy.

React Native 0.80 deprecates deep imports to reduce API surface area and stabilize usage: // ❌ Deprecated import { Alert } from 'react-native/Libraries/Alert/Alert'; // ✅ Use this instead import { Alert } from 'react-native'; You’ll now see ESLint and console warnings if you’re using internal paths. This cleanup makes room for a more maintainable and secure API layer. 💬 Have missing expo…  ( 5 min )

I started discovering OpenRewrite last week by writing a Kotlin recipe that moves Kotlin files according to the official directory structure recommendation. I mentioned some future works, and here they are. In this post, I want to describe how to compute the root package instead of letting the user set it. I developed last week a recipe to follow the Kotlin recommendation regarding directory structure: In pure Kotlin projects, the recommended directory structure follows the package structure with the common root package omitted. For example, if all the code in the project is in the org.example.kotlin package and its subpackages, files with the org.example.kotlin package should be placed directly under the source root, and files in org.example.kotlin.network.socket should be in the network/…  ( 8 min )

Here’s how you can spot a fake ATmega328P – a commonly counterfeited microcontroller, especially in Arduino-compatible boards: 1. Visual Inspection (ATmega328P) Markings: Genuine chips have clean, crisp laser markings or printing. Fakes may show blurry text, incorrect fonts, or an outdated/fake Atmel or Microchip logo. Suspicious Date Codes: For example, a chip marked with a 2024 date under the Atmel brand is suspicious, since Microchip acquired Atmel in 2016. Package Anomalies: Surface may show sanding or grinding (to re-label an old chip). Unusual finish (too shiny, too matte, or inconsistent with genuine chips). 2. Functional Testing Bootloader Issues: Bootloader flashing may fail. Programming via Arduino IDE may be unreliable or only work at 8 MHz (instead of 16 MHz). Unstable Behavior: EEPROM errors. Resets or crashes when power-cycled. Signature Mismatch: Use avrdude or similar tools to read the chip signature. bash avrdude -c usbasp -p m328p Expected signature: java Device signature = 0x1e950f Fake chips may return incorrect or inconsistent signature bytes. 3. ISP Programming Problems May have incorrect fuse bits. Could refuse to lock/unlock properly. Show strange behavior on SPI or other low-level protocols. 4. Electrical Behavior Higher-than-expected power consumption. Overheating even when idle. Unstable at lower voltages (e.g., under 5 V). 5. Supply Chain Checks Authorized distributors: Digi-Key, Mouser, Farnell, Arrow, Ampheo, etc. Trusted Arduino-certified vendors for official boards. Avoid: eBay, AliExpress, or other marketplace sellers offering very low prices or "bulk chips" with no traceability. 6. Community Knowledge Relabeled chips (e.g., ATmega8 or ATmega48 being sold as ATmega328P). Chips requiring modified bootloaders to work at all. You can check: EEVblog Forums Reddit /r/arduino Arduino forums for part number and batch discussions.  ( 3 min )

Linkerd automatically enables mTLS for all TCP traffic between meshed pods. To do so, it relies on several certificates that must be in place for the control plane to function correctly. You can supply these certificates during installation or generate them with third-party tools such as cert-manager or trust-manager. The required certificates are the Root Trust Anchor and an Identity Intermediate Issuer Certificate, which work together to issue a unique Leaf Certificate for every meshed workload. Linkerd’s Root Trust Anchor is a public CA certificate that serves as the ultimate trust point for all service-mesh certificates. It never issues workload certificates directly; instead, it signs intermediate CA certificates, which then issue the workload certificates. This separation lets each …  ( 6 min )

🧠 PHP Late Static Binding Explained: self:: vs static:: vs new static() for Real-World Use Hey fellow devs, Ever found yourself confused by the difference between self::, static::, new self() and new static() in PHP? I did too. Until I slowed down, played with examples, and finally understood the beauty of something called Late Static Binding (LSB). Let’s break it down like we’re talking over a project debug session. You have a parent class that defines a static method. You extend it with a child class and call the method from the child. But surprisingly, the method behaves like it’s still running in the parent. Like this: class ParentClass { public static function whoAmI() { echo "I am " . self::class; } } class ChildClass extends ParentClass {} ChildClass::whoAmI(); …  ( 5 min )

On Android devices, particularly those preloaded with Google services, you may notice a system app called Google Partner Setup running silently in the background. While it doesn't have a user interface or appear in your app drawer, it plays a crucial role in ensuring your device and certain apps function smoothly. But what exactly is it, and why is it running behind the scenes? Google Partner Setup is a pre-installed Android system component responsible for coordinating specific functions between the Android operating system and apps that rely on Google’s core services. It primarily helps manufacturers (like Samsung, Xiaomi, or Motorola) integrate their custom Android skins and features with Google's ecosystem, ensuring consistency, compliance, and usability. Google Partner Setup operates in the background because it supports critical functions that don't require user interaction. Here’s why this background process is necessary: 1. Syncing Device Features with Google Services 2. Enabling Device-Specific Customizations 3. Supporting App Compatibility 4. System Configuration at Boot 5. Ongoing Performance Adjustments Yes, Google Partner Setup is safe and necessary for most Android devices that rely on Google's core apps and features. It’s not spyware or bloatware, and removing or disabling it may disrupt system performance or cause sync issues with your Google account. While it is technically possible to disable Google Partner Setup using developer tools or ADB commands, it is not recommended. Disabling it can result in: Failure to sync contacts, calendar, or other Google services Google apps not functioning correctly Issues with system updates or manufacturer-integrated features Google Partner Setup runs in the background to ensure stable integration between Android, the device manufacturer’s features, and Google’s services. It may seem invisible to the average user, but its background activity is essential for a smooth and consistent Android experience.  ( 4 min )

A few weeks ago, I paid $3,000 for an AI mentorship program by Ritesh Verma. He runs a YouTube channel and a website called BecomeABotDeveloper, which promises to teach people how to build and sell AI agents. This is what the headline on the landing page said: “Make $5,000/month in 6 weeks building AI agents. Guaranteed income or your money back.” It sounded very convincing at the time. We had a video call, and I decided to join. The course mainly covered: Basic Puppeteer scripting for web scraping Some automation using n8n A bit of Reddit outreach strategy A short LinkedIn Sales Navigator video Mentions of tools like Apollo for cold emailing I found the technical content very basic — I’ve honestly seen better tutorials on YouTube for free. It felt more like a beginner-friendly automation overview, not an advanced mentorship on building or selling AI agents. Personally, the program did not meet my expectations. It was promoted as a business-building mentorship with a clear income promise, but what I got was surface-level automation content and vague outreach tips. There was a refund policy: if I stayed active for 4 weeks and didn’t get a project, I’d get my money back. I followed the rules, but received only a vague message about a “project” with no details. Eventually, after saying I might share my experience, I was refunded $1,200 — but I’m still down $1,800. If you’re reading this while researching Ritesh Verma or BecomeABotDeveloper, I hope this post gives you more context than just the marketing material.

Just recently saw this post and decided that it would be interesting to test out Amazon Q CLI capability by building a game, so here we go! First, I started by finding a game idea. Well turns out my high school teacher friend has some students find understanding physic concepts difficult, like free body diagrams. So I created this game for her students to understand the concepts easier~ With the game idea in place, I then proceed to setup the development environment and get my hands dirty. For anyone interested, you can refer this guide to install Amazon Q CLI. Basically Amazon Q CLI is like ChatGPT/Grok/DeepSeek but in the form of CLI, so it's quite easy to use as long as you are comfortable with CLI environment. So with Amazon Q CLI ready, now is time for prompting! It's working better than I expected as it appears Q is using a reasoning model by default, though the response time could be quite long as a trade-off. Therefore, after endless prompting and revising, i find the below tips that maybe usefull in facilitating effective prompting and reduce the back-and-forth between you and Q: Define a prompting framework such that the Q know the context, the task, and the expected results Ask Q to provide visual debugs can let the Q know how to fix issues more quickly Ask Q to give a plan before coding, that way you know Q is thinking as you expected With about 3 hours prompting and waiting, here's the final product! https://fbd.cmpapp.top GitHub: https://github.com/john-ng-hk/stem-fbd-game That's all and thanks for reading, feel free to connect me on LinkedIn too~  ( 3 min )

Microsoft Excel is more than just a spreadsheet application—it’s a foundational tool that transforms raw data into meaningful insights. From simple lists to complex data models, Excel provides a flexible environment for organizing, analyzing, and visualizing information across industries and disciplines. PivotTables: These allow me to summarize and analyze large datasets quickly. For example, I used a PivotTable to count product entries by rating category and discount level, helping me uncover patterns in pricing strategies. IF Function: The =IF () formula is incredibly useful for categorizing data. I applied it to group products into “Excellent,” “Average,” and “Poor” rating categories based on numeric thresholds, which made my dataset more meaningful. Data Sorting and Filtering: By combining Excel’s sorting tools with slicers, I was able to isolate top-performing products based on ratings, reviews, and discounts. This made it easier to create targeted visualizations and focus my analysis on what matters. Conditional Formatting: This feature highlights cells based on criteria, like coloring cells red for values below a threshold. It’s ideal for spotting outliers in financial data or tracking project deadlines. Learning Excel has completely reshaped how I view data. What once seemed like overwhelming numbers in rows and columns now feels like a story waiting to be uncovered. Excel has taught me that with the right tools, I can dig beneath the surface of data to find insights that are not only informative but transformative. It’s made me more curious, more confident, and more equipped to approach challenges—one cell at a time.  ( 4 min )

Hey devs! 👋 During a recent discussion with some colleagues about TypeScript decorators, we ended up deep-diving into Angular.dev and stumbled upon something interesting — the @Attribute decorator. Though it's not as commonly used as @Input, it's a powerful and underutilized feature in Angular. So, I wanted to take a moment to share what I learned about it, along with a real-world example. 🚀 @Attribute in Angular? The @Attribute decorator is a parameter decorator used in a directive's constructor to inject a host element's attribute value as a static string. It allows a class (typically a directive or component) to access a static HTML attribute value at construction time, even if it’s not bound to an Angular input. ✅ Great for static values from HTML attributes 🚫 Not reactive (doesn’…  ( 5 min )

What is Screaming Architecture? When you open a project, do you instantly know what it's about, or do you have to dig into the code to understand it?

When Databricks announced Lakebase, most people dismissed it as just another product. Even Databricks markets it as "the backend for AI Agents and Data Apps." This messaging puzzles me. It's the same pattern they followed with Delta Lake in 2019, positioning it as "bringing reliability to Big Data." But Delta Lake was actually much simpler: a transactional layer on top of an immutable object store. That's it. Yet this simple concept solved a massive architectural challenge—enabling storage and compute separation for data warehouses at scale. Storage and compute separation became the foundation for everything that followed: data sharing, unified storage formats, multiple query engines. But separation creates a problem: latency. For analytical workloads, this latency is manageable. For trans…  ( 4 min )
